Another new Caedium release and some interesting Computational Fluid Dynamics (CFD) applications - all in a month? That's right! You'll find a couple of new Caedium features that we couldn't hold back and a series of blog posts covering a virtual wind tunnel, a quadcopter, and 3D printing.

Helix Creation for CFD Simulations

The latest version of Caedium (v5.1) has a new Helix tool for your CFD simulations and improved mesh element size control. Read more >>

CFD Simulation of a Racecar in a Wind Tunnel

Having recently built a CFD simulation of the Honda Wind Tunnel at Imperial College, it seemed only fitting to actually use it to perform a virtual test on a scale model. Clearly, given the wind tunnel's close association with motor racing, the test model had to be a racecar. Read more >>

Wind Tunnel Explained With Computational Fluid Dynamics

Have you ever wondered what are the main features of a wind tunnel and what purpose do they fulfill? Well wonder no more. With the help of CFD let's explore a closed return wind tunnel based on the Honda Wind Tunnel at Imperial College, London. Read more >>

Moving Reference Frame for Computational Fluid Dynamics

A Moving Reference Frame (MRF) is a relatively simple, robust, and efficient steady-state, CFD modeling technique to simulate rotating machinery. For example, the rotors on a quadcopter can be modeled with MRFs. Read more >>

Simulation For Your 3D Printer

3D printers are the new black.

• "3D Printing will be bigger than the web", Chris Anderson, ex-Wired editor
• "Why MakerBot is Like Apple", John Biggs, TechCrunch
• In US$403M deal Stratasys buys MakerBot

Whether 3D printing can live up to the hype remains to be seen. However, making things has been around since time eternal. The fact that 3D printers have reached a price point allowing small businesses and hobbyists, collectively referred to as Makers, to leap on board is definitely exciting. However, what hasn't changed is that building a physical thing still costs time and money. What can we learn from the millennia of building things prior to the availability of 3D printers?
